Chiharu Arima decided she would spent the last days of her 18th summer back at her grandfather's hometown. There, she found an old mysterious letter that was from a person named Kaori Miyazono. *** Grandpa's room was dull. The smell of dust was all over the place. But this was a place full of memories... Every summer, he would teach me how to play the piano and even play the melodica. We always play Twinkle Twinkle Little Star together and I would sing it out loud. The pictures in his desk still remained. How old were these photos? 20? Maybe more than that. My eyes spotted a picture of him when he was a kid-he was behind with two young girls. That's strange...Why would he put a stolen photo inside a frame? Is it something special? Out of my curiosity I grabbed it and something strange fell as I took a hold of it. It was a letter. From Kaori Miyazono?
